The present invention relates to new and useful improvements in electric food mixers and more particularly to a heating attachment for various types of food while the same is being stirred by the mixer.

An important object of the invention is to provide a heating attachment which may be mounted on the usual base of an electric mixer without necessitating any changes or alterations in the construction of the latter and including a turntable rotatably supported above an electric heating coil and constructing the turntable to support a bowl for containing the food whereby the food may be heated or cooked as the same is being stirred by the mixer.

A further object of the invention is to provide an electric hot plate in which turntables of various types or sizes may be interchangeably and rotatably mounted.

A still further object is to provide a device of this character of simple and practical construction, which is efiicient and reliable in operation, relatively inexpensive to manufacture and otherwise well adapted for the purposes for which the same is intended.

Other objects-and advantages reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming part hereof, wherein like numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view;

Figure 2 is an enlarged vertical sectional view taken on the line 22 of Figure 1;

Figure 3 is a top plan view of the turntable, and

Figure 4 is a top plan view of the hot plate with parts broken away and shown in section.

Referring now to the drawings in detail wherein for the purpose of illustration I have disclosed a preferred embodiment of the invention, the numeral 5 designates a conventional type of electric food mixer which includes a hollow base 6 and standards 1 supporting the motor housing 8 in a position overlying the base, the agitator or beaters 9 extend downwardly from the outer end of the motor housing to enter a bowl ID in which the food to be stirred or agitated is placed.

The present invention comprises means for heating the contents of the bowl as the same is being agitated or stirred and includes an electric hot plate or unit II of insulation material having inner and outer electric heatin rings l2 and I3 recessed in concentric arrangement in 2 Claims. (01. 259 -s4) the upper surface of the hot plate ll. Circuit wires I4 lead from the rings l2 and l3-through a handle I 5 projecting radially from one edge of the hot plate to a temperature control switch or rheostat I6 secured to the side of the standard 1 by a clamp I1 and circuit wires I8 lead from the switch or rheostat Hi to a suitable source of current.

An eccentric lug l9 projects downwardly from the underside of the hot plate II to enter an opening in the upper surface of the base 6 to prevent the hot plate from turning on the base and a tapered hub 2| extends downwardly a central opening 22 in the base 6.

A cup or pan-shaped turntable 23 is mounted in spaced relation above the hot plate H by means of a shaft 24 at the underside of the turntable and secured at its upper end to the central portion of the turntable to extend downwardly in the hub 2|. Ball bearingassemblies 25 are secured to the shaft 24 and are fitted in the hub to rotatably support the shaft 24 therein.

The inside of the turntable 23 is formed with concentric stepped recesses 26 to receive bowls of various sizes and to hold the bowls from lateral shifting movement in the turntable.

The sides and bottom of the turntable 23 are formed with heating openings 2'! to expose the bottom and side portions of the bowl to the direct action of heat from the electric heating elements or rings l2 and I3.

In the operation of the device the hot plate II is placed in position on the base 6 of the electric mixer 5 and the turntable 23 with the shaft 24 projecting downwardly from the center Having described the invention, what is claimed as new is:

l. A heating attachment for electric food mixers having a base provided with a central opening, said attachment comprising a hot plate of insulation material having a tapered hub at its underside positioned in the opening for centering the hot plate on the base, a turntable having a shaft projecting downwardly therefrom, and tapered bearing means for the shaft and adapted for wedging self-supporting engagement in the central opening to rotatably support the turntable in an elevated position above the base.

2. A heating attachment for electric food mixers having a base provided with a central opening and an eccentric opening, said attachment comprising an electric hot plate having .a hub projectin downwardly at its underside positioned in the central opening and an eccentric lug at its underside positioned in the eccentric opening References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 1,174,031 Hadaway Feb. 29, 1916 1,944,245 Krause Jan. 23, 1934 2,016,554 Nichols Oct. 8, 1935
